Culm stout, about 3 mm across. Blade linear, up to 20 cm long, basal part covered with long hairs; ligule rounded, hispid on the backside. Inflorescence a large panicle, about 15 cm long by 5 cm wide. Spikelets paired, dimorphic, the upper pedicellate, pedicel with a translucent longitudinal groove; the lower sessile, lower; glume lanceolate, acute, chartaceous, 3-nerved, margins inrolled, about 3.6 mm long; upper glume chartaceous, ?-nerved, lanceolate, margins inrolled, ciliate on backside and margins, decorated with a concave spot on the upper part; upper lemma aristate, the awn 6 times the length of the lemma, flexuous, 1-nerved; upper palea hyaline, linear-lanceolate, margins folded, about 2.2 mm long; anther about 1.2mm long.Distributed in India and Malaya.
